Tungsten (W) yog cov khoom siv hlau nrog lub siab melting point, kub tsis kam, siab zog thiab siab hardness. Cov nplooj ntawv tungsten, uas yog cov ntawv nyias ua los ntawm tungsten, muaj ntau yam zoo ntawm lub cev thiab tshuaj lom neeg uas ua rau lawv siv dav hauv ntau lub teb.
Tungsten Sheet lub cev muaj zog
- High melting point: Tungsten muaj qhov melting point ntawm 3422 degree, siab tshaj plaws ntawm tag nrho cov hlau. Qhov no ua rau tungsten flakes nyob ruaj khov ntawm qhov kub siab heev thiab tsis yooj yim yaj lossis deformed.
- High Density: Qhov ceev ntawm tungsten yog 19.3 g / cm³, uas yog ze rau qhov ceev ntawm kub, yog li tungsten flakes muaj ib tug loj loj nyob rau hauv ib tug me me ntim.
- High Strength thiab Hardness: tungsten flakes muaj lub zog siab thiab hardness, thiab tuaj yeem tswj cov khoom no txawm tias qhov kub thiab txias.
- Tsawg Thermal Expansion: Tungsten muaj cov coefficient tsawg heev ntawm thermal expansion, uas txhais tau hais tias thaum kub kub nws muaj qhov me me hloov pauv thiab tsim nyog siv rau hauv qhov chaw thermal shock.
Tungsten Sheet tshuaj muaj zog
- Corrosion resistance: tungsten tiv taus ntau cov kua qaub, alkalis thiab tshuaj reagents, thiab tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab txias heev.
- Tsis tshua muaj tshuaj reactivity: tungsten tsis hnov mob yooj yim nrog oxygen, acids los yog alkalis ntawm chav tsev kub, ua rau nws ruaj khov nyob rau hauv ib puag ncig tshuaj.
Daim ntawv thov tungsten
- Kev lag luam kub kub: Txij li thaum tungsten flake tuaj yeem tswj hwm nws lub cev ntawm qhov kub thiab txias, nws yog dav siv hauv lub tshuab nqus tsev, cov khoom siv iav melting, thiab lwm yam khoom siv uas yuav tsum tau kho qhov kub thiab txias.
- Electronics thiab Semiconductor Kev Lag Luam: Tungsten flakes muaj cov hluav taws xob zoo thiab thermal conductivity, thiab feem ntau yog siv hauv cov dab dej kub rau cov khoom siv semiconductor, kev tsim khoom ntawm kev sib xyaw ua ke, thiab kev tsim khoom ntawm lwm yam khoom siv hluav taws xob.
- Aerospace teb: Hauv kev lag luam aerospace, tungsten flakes yog siv los ua cov ntaub ntawv tiv thaiv nrog rau cov khoom kub kub rau cov tshuab propulsion.
- X-ray thiab hluav taws xob tiv thaiv: Qhov siab ceev ntawm tungsten ua rau nws yog ib qho khoom siv tiv thaiv zoo rau X-rays thiab lwm yam hluav taws xob, thiab nws tau siv dav hauv kev kho mob thiab kev lag luam nuclear.
- Kev lag luam teeb pom kev zoo: Tungsten lub siab melting point thiab zoo hluav taws xob conductivity ua rau nws yog ib qho ntawm cov ntaub ntawv tseem ceeb siv nyob rau hauv kev tsim cov teeb filaments, tshwj xeeb tshaj yog rau incandescent thiab halogen teeb filaments.
tungsten ntawv ua thiab ntau lawm
Tungsten flakes feem ntau yog tsim los ntawm cov hmoov metallurgy, uas tungsten hmoov yog sintered, dov thiab forged ntawm qhov kub thiab txias los ua flakes. Qhov tuab thiab qhov loj ntawm tungsten flakes tuaj yeem kho kom haum rau ntau daim ntawv thov.
